We are professional sunflower
oil making machine manufacturer, Big scale sunflower oil
plant contains three workshops:sunflower oil press,
sunflower oil extraction and sunflower oil refining .Sunflower
oil making machine price is depending on the capacity you
required.
Process of sunflower oil making
machine
1. Sunflower oil
pre-press
process
First, using
magnetic roller , destoner and cleaning machine to remove
metals, small stones , impurities from sunflower raw seeds.
Second, using husking machine to
remove husks, separating screen to separate husk and sunflower
kernel , here separating screen must not separate
completely uf not it will be too slippery for oil
pre- press.
Third, cooking sunflower seeds ready for oil
pre-press
Fourth,
pre-pressing sunflower seeds. here only pre-press part of
sunflower oil , oil residue inside cake (about ****6%) will be
extracted in oil extraction process.After pre-pressed, the
crude sunflower oil will be delivered directly to
sunflower oil refining , and pressed cake to oil
extraction.
2. Sunflower oil extraction
process
First, using solvent to
extract oil from sunflower oil cake inside oil extractor,
final products are mixed oil and wet meal
Second, the
mixed oil will pass through three evaporators to make solvent
inside transform into gas , and solvent will be recovered
through condensers and reused. These three evaporators
are not with same size , the first evaporator is bigger than
other two because there are more solvent inside mixed oil in
the beginning . After evaporated, we will get crude sunflower
oil ready for oil refining.
Third, the wet meal will be delivered to
desolventizer to dry and be separated with solvent . The dry
meal will be packaged for sale as animal feed.
Note: Sunflower oil
extraction is more and more important in oil processing ,
because oil residue inside meal is less than 1% much less than
oil residue inside cake without
extraction.
3. Sunflower oil refining
process
First , hydrated degumming, mainly
is to remove phosphatide inside crude sunflower oil in order to
reduce oil loss and improve quality of oil .
Second, alkali refining, using alkali to
neutralize free fatty acid with by-product of soapstock ,which
is used for making soap.
Third,
decoloration using bleaching clay to absorb darker
colorant inside crude oil.
Fourth,
deodorization is using high temparature to remove the
impurities with bad smell .
Fifth, dewaxing is
using low temperature to freeze wax inside refined oil and then
separate wax with vibrating
screen.
